Difference between Lichee Tang nano and Lichee Tang

Hello
Could you tell me the difference between these 2 boards?
I’m seeing that the bigger Lichee Tang can use a debugger, i can actually debug with it or is it just a programmer? Do they have a way to get data fast from the pc? like 10mb/s or similar?
for example i’d like to use them with a ft232h in 245 sync mode which is a 8bit paralel fifo mode clocked at 60mhz, and i’d like to store the received data into sram to later write to a display, is something like this possible?
thanks
